How the system works
The principle is simple – and that's precisely why it's so efficient:
PV modules → Heating element → Hot water
The generated solar power is direct (DC-side) into the heating element.
There is no detour via inverters or the grid.
This means:
• No energy loss through conversion
• No feeding into the public grid
• No dependence on electricity prices
You use your solar power exactly where it is most beneficial: in the hot water storage tank.
Why better than classic solutions
❌ Feeding into the grid
• Low pay
• Dependence on the energy supplier
• Bureaucracy & Registration
❌ Inverter systems
• Conversion losses (DC → AC → heat)
• Higher cost
• More complex technology
❌ Gas / Electricity for hot water
• Running costs
• Price increases
• Fossil dependence
✅ PV heating element solution
• Direct consumption instead of feed-in
• No losses
• Immediate savings
• Maximum self-sufficiency
Technical highlights
Direct DC connection
No inverter required – maximum efficiency through direct use of solar power.
Stepless power control
It automatically adjusts to the available PV power.
High compatibility
Works with common PV modules and storage systems.
Self-sufficient operation
Ideal for off-grid systems or as a supplement to existing PV systems.
Who is this system suitable for?
✔ Homeowners with a PV system
✔ Users with high hot water demand
✔ Operators of off-grid systems ✔ Households with low feed-in tariffs
✔ For everyone who wants to sustainably reduce their energy costs
Typical pain point:
They produce electricity during the day – but do not consume it all.
👉 Solution: Storing hot water = storing energy.
Practical example – how much does it really help?
A 300-liter hot water storage tank:
• Starting temperature: 20 °C
• Target temperature: 60 °C
• Energy consumption: approx. 14 kWh
With a 3,6 kW PV heating element:
• Heating duration: approx. 4 hours at full power
• Usage: fully possible with solar power
👉 Result:
• Free hot water from solar energy
• Savings of several hundred euros per year
• Significantly higher self-consumption rate
Accessories & Extensions
For maximum efficiency, we recommend:
• PV modules (optimized for voltage & power)
• Suitable storage solutions for surplus electricity
• Smart meters for consumption optimization
• Expansion of existing PV systems
Tip: Combine the system with your existing PV system for maximum savings.
